Preble: Any Nation with Vast Power will be Tempted to Use It.

At WarontheRocks.com, Cato Institute vice president for defense and foreign policy studies, Chris Preble writes that “Any nation with vast power will be tempted to use it.” But perhaps after years of foreign adventurism with little to show for it, Americans are becoming warier of new interventions in foreign conflicts. Unfortunately, as Chris reports, Washington insiders haven’t seemed to have had their enthusiasm for meddling in world affairs dampened.

Any nation with vast power will be tempted to use it. In this respect, the United States is exceptional because its power is so immense. Small, weak countries avoid fighting in distant disputes; the risk that troops, ships, or planes sent elsewhere will be unavailable for defense of the homeland generally keeps these nations focused on more proximate dangers. The U.S. government, by contrast, doesn’t have to worry that deploying U.S. forces abroad might leave America vulnerable to attack by powerful adversaries.

There is another factor that explains the United States’ propensity to go abroad in search of monsters to destroy: Americans are a generous people, and we like helping others. We have often responded favorably when others appeal to us for assistance. Many Americans look back proudly on the moments in the middle and latter half of the 20th century when the U.S. military provided the crucial margin of victory over Nazi Germany, Imperial Japan, and the Soviet Union.

But, in recent years, Americans have grown more reluctant to send U.S. troops hither and yon. There is a growing appreciation of the fact that Washington’s willingness to intervene abroad – from Somalia and the Balkans in the 1990s, to Iraq and Afghanistan in the 2000s, to Libya and Yemen in the present decades – has often undermined U.S. security. We have become embroiled in disputes that we don’t understand and rarely can control. Thus, public anxiety about becoming sucked into another Middle Eastern civil war effectively blocked overt U.S. intervention in Syria in 2013, notwithstanding President Obama’s ill-considered red line warning to Bashar al Assad.

But while the American people are unenthusiastic about armed intervention, especially when it might involve U.S. ground troops, most Washington-based policy elites retain their activist instincts. They believe that U.S. military intervention generally advances global security and that the absence of U.S. leadership invites chaos. The essays in this series, “Course Correction,” have documented the many reasons why these assumptions might not be true. The authors have urged policymakers to consider other ways for the United States to remain engaged globally – ways that do not obligate the American people to bear all the costs and that do not obligate U.S. troops to bear all the risks.
